INTERPOSED WATER HEATER.

To all whom t may concern Beit known that 1, EDWARD. DavocK, a citizen of the United States, residing at New York, inthe county and State of New York, have invented certain new and useful Improvements in Interposed Water Heaters, of

i which-thefoiiowing is a ruil, Citar, and exact specification. y p

This invention relates tewater heaters for general kor domestic use in connection with r Y steam boilers, and it has for its object to coinbinea water vheater with a steam boiler in an improved manner, whereby the heat which usually. passes up the chimney and is lost may be utilized for heatingthe water for domestic or any other'desired use, and the supply of'hot waterfor. such 4purposes lmay designed :for

be provided as a resultof the ordinary operationrof ga steamjbciler without any additional expense Jfor fuel or attention.

. .Thewater heating attachment is especially steam boilers of the vertical sectional type, but may` also be used/with other styles, [The .inventionwill be hereinwhich .constitute part. oi"

defined'inf the 'claims atthe 'end ot the de-l scription.- .l

- similar reference characters are used to designate corresponding'parts throughout atfits sides and transverse water passages i heating system i of Figure 1. v

.The boiler may be composed of a plurality otV .vertical transverse sections 1 mounted upon a brickwork Yiioiuidation2 and each having water passages 3 extending vertically alternating with passages 5 for the products ofcombustion. Said passages5 of Vthe sev# eral. sections 1 constitute continuous longi tudinal'horizontal passages or flues which conii'nuiiicate with eachother viaa passage boiler is finished off with a front plate 1()v inthe front section. .Each section also has a ire space? above the grate 8, and an ash space 9 below said grate. The front of the ai'tferdescribed in connection with theaccom- .pany/ing drawings, y this specification,andthen lmore specifically,

Injthe accompanying drawings, wherein ure 1.

having a fire door 11 leading to the fire chamber, and an ash door 12 communicating with the ash pit. yEach vsection is further provided with a steam space 13 at its upper*y en d, said steam spaces in the several sections being connected up with one another by thimbles 14 iitted in registering openingsl.

l/Vater is supplied to the water passages 3 of the sections 1 near the bottom thereof by pipes 16 and circulates through said passages 3 and the transverse water'passages 4 communicating therewith, asindicated by the doubleheaded arrows in Figure 2, until iti reaches the steamV dome composed by the communicating steam spaces 13 vat the top of the boiler where the Lsteam separates from the water Vand escapes through thev pipes 17. The products of combustion pass from the rear end of the lire box into `the flue space 18 at the back of the boiler, thence through the lower of the` passages or flues 5 to the front of the boiler, thence upwardr` i through passage 6in the front section, and' thence vrear/ward in the upper iiue` 5 tothe flue space 19. atl the rear end of the boiler, as l vindicated by the single headed arrows inFigure 1. y, p .y f ,y

it the rear end of theboiler there is a. casing 2() lsupported 'upon a brickwork foun-` dation 21.and vertically'and transversely arrauged'insaid casing is a chambered partitiou 22lconstituting the rear walls ofthe flue spaces 18 and 19 yalready` referredtog.

said flue spaces being separated .from one another bya horizontal transverse partition plate 23 bolted/or otherwise secured t0. ther front. wall ot' said chambered partitiony v22 between the lower and upper boiler flueskp and extendingfroin said. chambered partitiouto meet the rear face of the rearmost section of the boiler,as clearly shown in F igi'utes the auxiliary water yheater .in which water is heatedby the products of combus-` tion ontheir way to the chimney. After` reaching.' the flue space 19, as already ex;

plained, thefproducts of combustion pass through a passage 24 inthe upper portion of. the chainbered partition otA water heater 22v into vanother. flue space 25 at the rear ofv saidpartition orwater heater, vand thence downward inthe casing 2O to the chimney 26 which communieatesA with said casing and rear liuc space 25 near the bottonithereof, as

also. indicated byfsingleheaded arrows infr Figure 1. y
